Succession planning secured in Bühler Group’s leadership

Ad hoc announcement pursuant to Art. 53 LR

Uzwil (Switzerland), April 24, 2025 – Bühler Group remains committed to its long-term orientation as a family business. Through proactive personnel and leadership planning, Bühler ensures continuity and stability for its employees, customers, and partners. The Board of Directors is therefore announcing the upcoming succession plans for 2026. 

The Board intends to appoint Samuel Schär as the new CEO as of January 2026.  

Samuel Schär studied physics at EPFL Lausanne. After gaining initial experience in consulting, he joined Bühler 20 years ago to establish the Nanotechnology business unit. He then led the Grinding & Dispersing business area for several years, before joining the Group Executive Board in 2013 and successfully leading the Advanced Materials segment for 10 years. He later took over responsibility for the Global Services & Sales organization.  

In parallel, the Board of Directors has decided to propose Stefan Scheiber as the new Chairman of the Board of Directors of Bühler Group at the next Annual General Meeting in February 2026.  

Stefan Scheiber looks back at a successful 35-year career at Bühler in Switzerland and abroad. He has been a member of Group Management for 20 years in various areas of responsibility and will have held the position of CEO for 10 years at the end of this year.  

Stefan Scheiber will succeed Calvin Grieder. Calvin Grieder will step down at the 2026 Annual General Meeting after 25 successful and formative years as CEO, Member of the Board of Directors, and Chairman of the Board of Directors of Bühler Group.  

This long-term succession plan follows the transition initiated years ago within the owner family by Urs Bühler. The fifth generation of the family – Karin, Maya, and Jeannine Bühler – are continuing the long-term ownership strategy. Bühler will remain in the ownership of the family and will continue to pursue the goal of remaining successful as an independent, globally active technology company.
